在此處右鍵察看源代碼并把其中的js保存為splitter.js<br>
splitter.js使用方法：<br>
頁面上需要有一個div作為容器(id=splitter_container): 可拖動效果就在這個容器里面進行<br>
容器里面需要有3個div,分別代表左欄(id=splitter_left_panel)，分割線(id=splitter_bar), 右欄(id=splitter_right_panel)<br>
這4個div需要用css修飾一下<br>
<code>
#splitter_container{
width: 100%;
height: 100%;
border: solid #eee 1px;
margin: 0px;
padding: 0px;
overflow: hidden;
}<br>
#splitter_left_panel{
width: 300px;
height: 100%;
float: left;
border: solid blue 0px;
}<br>
#splitter_bar{
width: 8px;
height: 100%;
float: left;
background-color: #ccc;
cursor: col-resize;
}<br>
#splitter_right_panel{
height: 100%;
padding-top: 10px;
}
</code>
<br><br>
給body加上onload事件處理函數,以觸發splitter: <br>
onload="Splitter.init({id: 'splitter_Container', isWidthLimit: true});" <br>
Splitter的init方法傳入一個json對象作為配置參數,其中容器id是必需的.<br>
還可以配置更多的參數, 比如:<br>
isWidthLimit: 可選值true, false, 設置左面板是否限制寬度;<br>
lPanelMaxWidth: 左面板最大寬度,比如: 500px;<br>
lPanelMinWidth: 左面板最小寬度,比如: 100px;<br>
barActiveColor: 分割線拖動的時候的顏色: 比如'red', '#0080ff';<br>
